Application filed November 7, 1921.

To all whom itmaz concern:

Be it known that I, JULIUS P. Earn, a

citizen of the United States, and resident of Milwaukee, in the countyof Milwaukee and State of Wisconsin, have invented new and usefulImprovements in Dumping Bodies for Vehicles, of which the following is adescription, reference being had to the accompanying drawings, which area part of this specification.

This invention relates to improvements in dumping bodies for vehiclesand more particularly to a dumping body normally positioned on the frameof the vehicle in load retaining position but capable of moving relativethereto in load discharging position; and one of the objects of theinvention is to provide novel "means for limiting rearward movement ofthe body relative to the frame.

A futher object of the invention is to provide means adapted to limitrearward movement of the body relative to the frame which means iscapable of cushioning the shock that occurs when the body reaches itsload discharging position and which is also capable of aiding in tiltingthe body from its normal position and in returning the body to itsnormal or load retaining position.

The invention contemplates the provision of a dump body of such shapethat it may be readily tilted to the rear with respect to the vehicle;and a further object of the invention is to provide novel means ofsimple construction for retaining the body in its normal or loadretaining position whereby upon release of said means, the body mayeasily be moved into its load discharging position.

The invention also contemplates the provision of bearing means providedon the frame of the vehicle which isengaged by suitable bearing meanscarried by the body of the vehicle when the body is in its loaddischarging position; and a further object of the invention is toprovide bearing means on the frame of the vehicle which is ada ted to beengaged by suitable means carrie by the body of the vehicle the momentthe body be ins to move out ofits normal position, w reby the body issupported while Serial No. 513,542.

moving from its normal into its load discharging position.

The invention consists in the novel constructions, arrangements anddevices to be hereinafter described and claimed for car-' rying'out theabove stated objects and such other objects as will appear from thefollowing description of a certain preferred embodiment illustrated inthe accompanying drawings, wherein- Fig. 1 is a side elevational view ofa fragmentary portion of a vehicle equipped with a dump body andembodying the principles of the invention, the dum body being shown inits normal or loa retaining posltion;

Fig. 2 is a side elevational view similar to Fig. 1 but showing the bodyin its dumping or load discharging position;

Fig. 3 is a sectional view, on an enlarged scale, taken on the line 33of Fig. 1;

Fig. 4 is a view, on a still larger scale,

taken on the line l-4 of Fig. 3; and

Fig. 5 is a detail view showing the means preferably employed forlimiting movement of the body relative to the frame.

Referring now to the drawings, it willbe seen that the chassis of thevehicle includes a pair of.longitudinally extending channel members 7 tothe upper horizontal flanges of which are" secured channel members 8,respectively, and on which the bottom 10 of the dump body 9 rests whenthe latter is in its normal or load retaining position,

as shown in Fig. 1.

The center of gravity of the dump body is such that it may readily betilted to the rear of the vehicle and means is provided, therefore, tohold the body in its normal osition, which means preferably includesracket members 11 see Fig. 4, secured to the upperv horizontal-flangesof the res ective channel members 8, each of whic is provided with atooth- 12. On the front side of the body and secured thereto in anydesired manner is a pair of bracket members 13 in which is journaled atransversely extending rod 14 provided with an operating handle 15 ateach end. Rigidly secured to the rod 14. are catch members 16 which areadapted to engage the respective teeth formed on the bracket members 11.The

handle 15 of the rod 14 normally hangs pendant and maintains the latchmembers 16 in operative engagement with the catch members 11. Ifdesired, compression springs 17 may. be interposed betweenthe body andthe upper ends of the'latch members 16 to insure the latch members'beingmaintained in operative engagement with the catch members at all normaltimes. Plates 18 are preferably secured to the front side of the body,the lower ends of said plates being bent, as shown in Fi 4, to bear onthe brackets 11 when the b0 y is in its normal position. v The members 8at their rear ends are rounded .ofi'as at 19 and-each member has securedthereto a bearing block 20 and a bearing bracket 21. The body-isreinforced by securing channel irons 22, 23 and 24 to its front, bottomand. rear sides, respectively, which channel members are in line withthe frame members 8. These channel members are positioned with their-"bcks against the dump body so that the fla ges of the channel members 23e'fi'e'ctivel prevent lateral movement of the body, w enin it normalposition, relative to the frame. Bearing pins 25 and 26 are journaled inthe respective channel members 24:, these .pins being so arranged thatthe pins 25 coengage with the bearing blocks 20 immediately the dumpbody begins to move from its normal position into its load dischargingposition, and when in' its latter positlon, the pins 26. co-engage withthe bearing brackets 21 and support-the body. The bearing pins 25 serveto support the body and guide it while it is swinging from its normalinto its load discharging position, and vice ve'rs'a. v

The means to limit rearward'movement of the body relative to the frame,when the body is swin 'n into its load discharging position, pre era lyincludes a pair of rods 27 pivotally connected at their upper ends toplates 28 riveted to the respective channel members 24, the lower endsof said rods projecting through apertures 30 provided in a transverselyextending member 29 secured to the frame members 8. A stop member,preferably in the formof a nut 31, is provided on the lower end of eachof the rods 27 and a relatively sion sprin 32 encircles t e lowerportion of each 0 the rods 27, said spring being interposed between thenut 31 and the cross member 29.

The operation of the dumping body will be apparent from the foregoingdescription, but may be summarized briefly as follows :--Assuming thebody is loaded and is in the position shown in Fig. 1 it will be obviousupon releasing the latch members 16 from engagement with the rtive heavycompresaser catch members 11, that the body may be easily swung into itsload discharging position, the bearing pins 25 first coming intoengagement with the bearing blocks 20 and ivotally supporting the bodyuntil the caring ins 26 come into engagement with the bearingbrackets2l. Upon the bearing pins 26 coming into engagement with bearingbrackets 21, the body continues to turn over rearwardly, its rearwardmovement being checked by the rods 27 and the com-- pression springsassociated with said rods. The compression springs absorb the shockwhich occurs when the bearing pins 26 strike the bearing brackets 21 andupon the load being discharged from the body, said springs act to aid 1nreturning. the body'to its normal-or load retaining position.

the body swings back into its normal position, the latch members 16automatically swing into operative engagement with the catch members 11.The body being designed so 'thatit may easily be swung from its normalposition into its load discharging position, it requires very littleeffort on the part of the operator to dump the body once the latchmembers have beenreleased from the catch members. By providingcompression springs of suitable strength, the body may be returned toits normal position with very little efi'ort on the part of theoperator. The rods 27 and the compression springs preferably are sodesigned that they not only cushion the shock and aid in returning thebody to its normal position as described, but they also aid in tiltingthe body when it is in its normal positiomthe springs being under somecompression when the body is in its normal position.

The combination with the frame of a vehicle, of a body normallypositioned on the frame in load retaining position but capable ofmoving-relative thereto into load discharging position, a rod slidablyengaging a portion of the frame and pivotally connected at. one. end tosaid body, a stop on said rod, and aspring encircling said rod andinterposed between ,saidstop and said ortiono'f the frame, for thepurpose speci ed.
